从斐济植物大戟属（Euphorbia fidjiana）的心材中分离出3个新的对洋桃仁-3- 1,1个新的对洋桃仁-二烯二萜，以及已知的化合物jolkinolides a和e。这些化合物的结构和相对立体化学已通过高场核磁共振研究确定。的结构。根据核磁共振数据和x射线结构分析确定了-内酯。对先前报道的假jolkinolides的结构进行了修正。
The heartwood of the Fijian species Euphorbia fidjiana has yielded three new ent-pimaren-3-ones, a new ent-abietadienoide, as well as the known compounds jolkinolides A and E. The structures and relative stereochemistry of the ent-pimaren-3-ones have been determined from high field NMR studies. The structures of the .gamma.-lactones were assigned on the basis of NMR data and an X-ray structure analysis. The structures of the previously reported pseudojolkinolides have been revised.
